Abstract: 916,795. Digital calculating; checking. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 10, 1960 [Feb. 24, 1959], No. 4721/60. Class 106 (1). An adder performs addition, or subtraction by complement addition, and simultaneously adds the complements of the numbers operated on, a check being made that the results, and preferably any carries arising during the operations, are complementary. Fig. 3 shows three stages or orders of a parallel adder or subtracter in which binary digits to be operated on are stored in flip-flop registers, e.g. 2E, 3E. Stage E also comprises a set of gates 40E, two adders 5E and 6E, utilizing exclusive-or circuits designated #, exclusive-or circuits 7E, 9E used as comparison circuits and flipflop 4E storing the result of the operation. An addition signal on line 47 opens gates 41E and 42E resulting in the signals on the " 1 " outputs of flip-flops 2E, 3E being supplied to adder 5E. Carry from the previous odrer is marked on line 19E while if there is carry from stage E the output of or circuit 17e is high. If the sum is 1 the output of circuit 21E is high. Simultaneously with the true addition of the contents of flip-flops 2E, 3E in adder 5E addition of the complements is effected by gating the " 0 " outputs of the flipflops to adder 6E. The carries from adders 5E, 6E are applied to circuit 9E and if these are complementary a check signal issues. Similarly the results of the addition in adder 6E is applied to circuit 7E together with the " 1 " output of flip-flop 4E. Again, if these are complementary a check signal issues. For subtraction gates 43E and 44E are opened, connecting the " 1 " output of flip-flop 2E, and the " 0 " output of flip-flop 3E to adder 5E, the other outputs to adder 6E. The digit in flip-flop 3E is subtracted from that in flip-flop 2E by complement addition ; the complements of these digits are operated on in adder 6E and the results and borrows compared in circuits 7E, 9E.

Abstract: 688,797. Winding yarns. CELANESE CORPORATION OF AMERICA. March 2, 1951 [March 4, 1950], No. 5117/51. Class 120(ii) A method of making packages of uniformly twisted yarn by collecting on a rotating package support yarn drawn from a supply package that is rapidly rotated so as to twist the yarn comprises initiating the rotation of said supply package while collecting yarn drawn from said supply package as a winding axially spaced from said package support and leading the yarn from said winding to said package support when said supply package has attained full twisting speed. As shown, apparatus for carrying out the above includes a supply bobbin 11 mounted on a spindle 12 rotated by any suitable means. Yarn 13 is drawn upwards from bobbin 11, passed through pigtails 14 and 15, across a bar 16, and is directed during normal winding by reciprocating traverse guide 17 on to a tubular support 19. A mandrel 23 engages the interior of the support 19 and is mounted for free rotation on a bracket 24 which pivots about a rod 25. Mandrel 23 is provided at its free end with a plurality of projecting pins 26. The yarn rests against the surface of one of a pair of cork-covered rolls 27 fastened to shafts 28 (one only shown) journalled in bearings 29 and positively driven. A reduction gear 31 is driven from shaft 28 through suitable gearing and the output of gear 31 drives a cam 34 which, on rotation, causes the reciprocation of a rod 35 urged into contact with cam 34 by compression spring 38. On the underside of rod 35 is a rack segment 41 which engages a pinion 42 fastened to a shaft 43 carrying at its free end, and close to the pins 26, a finger 45. At the commencement of the winding of a cheese, yarn 13 is manually looped round the pins 26, the bobbin 11 is started and the bracket 24 is lowered to bring support 19 into contact with the rotating roll 27. The yarn 13 is dropped over the finger 45 which guides the yarn on to the pins 26 to form a winding 46. After all the untwisted yarn has been wound on the pins 26, the rotation of cam 34 causes counter-clockwise rotation of finger 45 so as to lead the yarn to the end of the support 19, where a transfer tail 47 is wound into groove 21 and further rotation of finger 45 permits the yarn 13 to slip off the finger 45 and to be picked up by the reciprocating guide 17 to wind the cheese proper.
